The Centers for Disease Control and Prevention clarifies that community spread means the spread of an illness for which the source of infection is unknown. The term is used when officials cannot determine how a person contracted the virus.

Emerick said the new case "is not person-to-person [in San Antonio]. It is travel-related."

The patient, who's in stable condition, began showing symptoms in early March before testing positive for COVID-19 on Thursday. Now, they are in self-quarantine along with their family.

Metro Health is conducting an extensive investigation to identify people who may have come in contact with the individual.

In response to the confirmed case, San Antonio officials declared a public health emergency that prohibits gatherings of 500 people or more. Fiesta San Antonio has been postponed to November and the Oyster Bake has been canceled.
